icd 10 cm code for hypertension due to primary malignant neoplasm of brain
The ICD-10-CM code for hypertension depends on the specific type of hypertension. For essential (primary) hypertension, the code is I10. If the hypertension is secondary, it involves a different category, like secondary hypertension (I15), which is caused by another condition.
Here are the codes for different types of hypertension:
I10: Essential (primary) hypertension, also known as high blood pressure.
I11: Hypertensive heart disease.
I12: Hypertensive chronic kidney disease.
I13: Hypertensive heart and chronic kidney disease.
I15: Secondary hypertension, which has sub-codes for specific causes like endocrine disorders or renal disorders.
I16: Hypertensive crisis.
I1A: Other hypertension.
Important Considerations
Documentation is Key:
A new diagnosis of hypertension requires clear documentation, as an elevated blood pressure reading alone without a diagnosis is coded differently.
Comorbidities:
Codes are also available for hypertensive disease complicating pregnancy and for conditions like benign intracranial hypertension.
Specificity:
The most appropriate code depends on whether there is a specific underlying cause or if the condition involves the heart, kidneys, or both.
